FloDB

Unlocking memory in persistent key-value stores

FloDB is a persistent key-value store that exploits large DRAM capacities on multi-core servers by maintaining a multi-level architecture: a small concurrent in-memory buffer feeds a larger DRAM-resident skip list, which is periodically flushed to an LSM-tree on persistent storage. This design decouples memory bandwidth from I/O bottlenecks, achieving high throughput on write-heavy workloads.
